    Abstract: Abstract— Xylophragma (Tribe Bignonieae, Bignoniaceae) includes seven species of lianas or scandent shrubs. The genus is characterized by leaves 1‐5-foliolate with a simple tendril replacing the terminal leaflet, branched trichomes, calyx usually cuspidate, pink flowers, and ovary usually lepidote. The genus is distributed through dry forests from Mexico to Paraguay and Southern Brazil. We provide the first comprehensive taxonomic treatment for Xylophragma , including a detailed description of the genus, a key for all species, complete list of synonyms, descriptions and illustrations for all species, as well as information on the geographic distribution, habitat, phenology, conservation status, and taxonomic comments for all taxa. Overall, we analyzed more than 700 sheets deposited in 13 herbaria, including types for all accepted names and synonyms. We designate lectotypes for Arrabidaea clausseni , Arrabidaea elliptica , Arrabidaea macrophylla , Rojasiophyton tuberculatum , Saldanhaea myriantha var. pubescens , and a second step lectotype for Distictis rovirosana . Four new synonyms are proposed: A. claussenii as a synonym of X. corchoroides; S. pratensis and R. tuberculatum as synonyms of X. myrianthum ; and X. unifoliolatum as a synonym of X. seemannianum .

    Abstract: Abstract— Adenocalymma is a genus of Neotropical lianas, shrubs, and treelets that belongs to tribe Bignonieae (Bignoniaceae). The genus is recognized by the cupular trichomes found on the prophylls, bracts, bracteoles, calyces, and fruits, and the presence of articulated petioles and petiolules. A recent molecular phylogeny of Adenocalymma recovered all three species of Neojobertia as well as Pleonotoma albiflora nested within the genus, indicating the need for an updated circumscription. Molecular phylogenetic results combined with morphological data also revealed the need for a revised circumscription for several species. Here, we present an updated circumscription and synopsis of Adenocalymma that recognizes 76 species within the genus. New combinations are proposed for N. alboaurantiaca , N. candolleana , and N. mirabile . Lectotypes are proposed for A. longeracemosum, A. nodosum , and A. validum , a neotype is proposed for A. paucifoliolatum , and an epitype is designated to support the lectoype of A. trifoliatum . In addition, twelve new synonyms are proposed as follows: 1) A. croatii is synonymized under A. biternatum ; 2) A. aspericarpum is synonymized under A. cladotrichum ; 3) A. fruticosum is synonymized under A. hyposticum ; 4) A. apterospermum is synonymized under A. marginatum ; 5) A. campicola is synonymized under A. nodosum ; (6, 7, 8) A. axillare , A. bipinnatum , and A. paucifoliolatum are synonymized under A. peregrinum ; 9) A. involucratum is synonymized under A. pubescens ; 10) A. reticulatum is synonymized under A. scabriusculum ; 11) A. pseudopatulum is synonymized under A. schomburgkii ; and 12) A. prancei is synonymized under A. subincanum .

    Abstract: Abstract— The Amazon houses a large proportion of the overall biodiversity currently found on Earth. Despite that, our knowledge of Amazonian biodiversity is still limited. In this study, we reconstruct the phylogeny of Pachyptera (Bignoniaceae), a genus of neotropical lianas that is centered in the Amazon. We then use this phylogenetic framework to re-evaluate species limits and study the biogeographic history of the genus. We sampled three molecular markers (i.e. ndhF, rpl32-trnL , and PepC ) and 51 individuals representing the breadth of morphological variation and geographic distribution of all species recognized in the genus. We used this information to reconstruct phylogenetic relationships among individuals of Pachyptera using Bayesian and maximum likelihood approaches. The resulting molecular phylogeny was used as a basis to test species limits within the P. kerere species complex using a cpDNA coalescent approach (GMYC). GMYC identified five potential species within the P. kerere species complex that were subsequently evaluated in the light of morphology. Morphological data supported the recognition of four of the five potential species suggested by GMYC, all of which were also supported by a multispecies coalescent model in a Bayesian framework. The phylogeny of Pachyptera was time-calibrated and used to reconstruct the biogeographical history of the genus. We identified historically important migration pathways using our comprehensive cpDNA dataset and a Bayesian stochastic search variable selection (BSSVS) framework. Our results indicate that the genus originated in lowland Amazonia during the Middle Eocene, and subsequently occupied Central America and the Andes. Most of the diversification of Pachyptera occurred in the Miocene, a period of intense perturbations in South America.
